The mafia's code of silence is nothing compared to the Kardashians'! RadarOnline.com has learned that new mom Kim Kardashian is lashing out at her BFF Jonathan Cheban and threatening to ban him from Keeping Up With the Kardashians if he talks about her on a new show.
"Kim is furious with Jonathan because he's going to be on Celebrity Big Brother in the UK and she's afraid he's going to spill all her secrets," a source told Radar.
"She gave him an ultimatum, telling him that she didn't want him to do the show and if he did, she would stop talking to him."
The source explained that Kardashian, 35, warned Cheban, 41, not to gossip about her.
"Kim thinks that fame has gone to Jonathan's head. She told him that she doesn't want him to do the show and if she does she might not let him do KUWTK anymore," the insider claimed.
